Cement enhancer

I. Product Introduction 
This series of cement strengthening agents are liquid products mainly composed of organic carboxylates, alkanolamines, polyols, and other inorganic salts as auxiliary components. They are generally brownish-transparent, odorless, non-irritating, and do not harm human health or the workability of cement concrete. 
Specifications: 250 kg/barrel, 1 ton/barrel, and bulk packaging. 
Density: (20℃±1℃) 1.10-1.30 (g/cm³) 
PH value: (20℃±1℃) 8～11 
Solid content: 35～65 (%) 
Product shelf life: 12 months. The use of the product in cement does not affect the shelf life of the cement. 
Recommended dosage: 0.03-0.2% (m/m) of the cement weight.

II. Scope of Application and Effects 
This series of cement strengthening agents are mainly applicable to silicate cement, ordinary silicate cement, composite silicate cement, slag silicate cement, fly ash silicate cement, masonry cement, and volcanic ash silicate cement. By further stimulating the mineral components in the cement, the product increases the amount of cement hydration products, improving cement quality. This achieves a reduction in the amount of cement clinker used and improves the overall efficiency of cement production. 
Using this product in addition to existing grinding aids, while maintaining consistent cement fineness control indicators, can further reduce the cement clinker usage by more than 4% and increase the cement mill output per unit time by more than 8%, while maintaining or slightly improving the cement workability.

IV. Cement Characteristics When Using This Cement Strengthening Agent 1. The flowability of the cement powder will increase; 
2. The flow of cement mortar will slightly increase; 
3. The water requirement for standard consistency will slightly change (when the type and amount of admixture are the same); 
4. Setting time will slightly prolong; 
5. The 45μm residue of the cement will decrease, while the specific surface area will not increase. The 45μm residue should be used to control the grinding fineness. 
V. Storage Method and Conditions

This series of cement strengthening agents are weakly alkaline liquids. It is recommended to use plastic storage equipment for airtight storage. The storage equipment should be equipped with a circulation device, and the product should be regularly circulated to ensure uniformity. The recommended storage temperature is -10℃ to 40℃. 
VI. Adding Method During Use

When no heightening of the addition is required, a metering pump can be used for direct metering and addition; 
When it is necessary to increase the feeding height of the cement strengthening agent, a two-stage pumping method is generally used. 
VII. Precautions

1. This cement strengthening agent should be used after passing inspection. Inspection methods include: 
(1) A simple method is to measure the density, PH value, color, or solid content of the newly received cement strengthening agent and the sample of the cement strengthening agent that has been proven qualified under the same temperature conditions. If the two are within the error range, it can be considered qualified for use; 
(2) Use a cement without additives that has the same composition as the produced cement. In the same laboratory, cement strength tests are conducted using both a qualified sample of the cement strengthening agent and a sample of the newly received cement strengthening agent. If the three-day strengths of the two are within the error range, it is considered qualified; 
When using the cement strengthening agent continuously, generally one method is used. The two methods are used only when there is a significant discrepancy in the quality of the cement strengthening agent. 
2. When handling and storing barrelled cement strengthening agent, avoid dropping, smashing, external force pressing, and proximity to high temperatures. The stacking height should not exceed two barrels; 
3. Check the company's label before opening the seal, and confirm that the product and model are correct before use; 
4. This product has mild corrosive properties to the skin. After skin contact, rinse with water immediately. Do not ingest; 
5. When using this product, if the ambient temperature is continuously below -5℃ for 5 days, insulation measures should be taken to prevent the product viscosity from increasing and affecting normal use; 
6. Shelf life of this product: 12 months.
